Paper ejecting device

Abstract

Curling of a printed sheet is corrected, friction is reduced on a paper transport surface, and the shape of the printed and ejected sheet is adjusted to a predetermined shape.

1. A paper ejecting device, comprising:
 a body having suction transport belts for transporting a sheet of paper along a paper transport surface of the body by suction; 
 jumping boards provided on both sides of the body along a paper transport direction; and 
 a curling corrector for correcting a shape of the sheet along paper transport surfaces of the jumping boards, 
 wherein the curling corrector is made up of a sucker for sucking the sheet on the paper transport surface of the jumping board. 
 
     
     
       2. The paper ejecting device according to  claim 1 , wherein the jumping board has a friction reducer on the paper transport surface, the friction reducer reducing friction with the sheet, and the friction reducer is made up of a plurality of rollers provided on the paper transport surface of the jumping board. 
     
     
       3. The paper ejecting device according to  claim 1 , wherein the jumping board has a friction reducer on the paper transport surface, the friction reducer reducing friction with the sheet, and the friction reducer is made up of a suction transport belt for transporting the sheet along a paper transport surface of the suction transport belt by suction. 
     
     
       4. The paper ejecting device according to  claim 1 , wherein the curling corrector is made up of an air blower for blowing air so as to press the sheet to the paper transport surfaces of the jumping boards. 
     
     
       5. The paper ejecting device according to  claim 4 , wherein the air blower blows air from a center of the sheet to both ends of the sheet, the ends being disposed in parallel with the paper transport direction. 
     
     
       6. The paper ejecting device according to  claim 3 , wherein the body and the friction reducer can adjust transport speeds of the suction transport belts. 
     
     
       7. The paper ejecting device according to  claim 1 , wherein in the curling corrector, the sucker is made up of an air sucker capable of adjusting an air suction force. 
     
     
       8. The paper ejecting device according to  claim 1 , wherein the jumping board has the paper transport surface which can be tilted at any angle relative to the paper transport surface of the body and can be moved to any position in a direction orthogonal to the paper transport direction. 
     
     
       9. A paper ejecting device, comprising:
 a body having suction transport belts for transporting a sheet of paper along a paper transport surface of the body by suction; 
 jumping boards provided on both sides of the body along a paper transport direction; and 
 a curling corrector for correcting a shape of the sheet along paper transport surfaces of the jumping boards, 
 wherein the curling corrector is made up of an air blower for blowing air so as to press the sheet to the paper transport surfaces of the jumping boards. 
 
     
     
       10. The paper ejecting device according to  claim 9 , wherein the air blower blows air from a center of the sheet to both ends of the sheet, the ends being disposed in parallel with the paper transport direction.
